D. -2
Correct Answer
C. C. -1Explanation
The given sequence follows a pattern where each term is obtained by subtracting 3 from the previous term. Therefore, starting from 17, we subtract 3 successively to get the next terms: 14, 11, 8, 5, 2. The 7th term can be found by subtracting 3 from the 6th term, which is -1. Hence, the correct answer is C. -1.Rate this question:

Seutas tali dipotong menjadi lima bagian sehingga panjang masing-masing bagian membentuk pola barisan bilangan. Jika panjang tali terpendek 10 cm, tali yang di tengah 20 cm dan tali terpanjang 30 cm, maka panjang mula-mula adalah ....

Correct Answer
D. D. 100 cmExplanation
The question states that a rope is cut into five pieces, forming a sequence of numbers. The shortest piece is 10 cm, the middle piece is 20 cm, and the longest piece is 30 cm. To find the initial length of the rope, we need to find the common difference between the lengths of the pieces. Since the lengths form an arithmetic sequence, the common difference is the difference between any two consecutive terms. The difference between the middle piece (20 cm) and the shortest piece (10 cm) is 10 cm. Therefore, the common difference is 10 cm. To find the initial length of the rope, we need to subtract four times the common difference from the longest piece. 30 cm - (4 * 10 cm) = 30 cm - 40 cm = 100 cm. Therefore, the initial length of the rope is 100 cm.Rate this question:

Diketahui titik K(7, a) dan titik K berjarak 7 satuan dari sumbu-Y dan berjarak 6 satuan dari sumbu-X serta berada di bawah sumbu-X, maka nilai a adalah....
- A.
A. – 7
- B.
B. – 6
- C.
C. 6
- D.
D. 7
Correct Answer
B. B. – 6Explanation
The point K is given to be (7, a). It is mentioned that K is 7 units away from the y-axis and 6 units away from the x-axis, and it is located below the x-axis. This means that the y-coordinate of point K is negative. Since K is 7 units away from the y-axis and below the x-axis, the y-coordinate must be -7. Therefore, the value of a is -7.Rate this question:

Diketahui titik A(4,2), B(4, 7), dan C(-1,7). Jika ketiga titik dihubungkan akan membentuk ....
- A.
A. Segitiga sama sisi
- B.
B. Segitiga siku-siku
- C.
C. Segitiga sama kaki
- D.
D. Segitiga siku-siku sama kaki
Correct Answer
B. B. Segitiga siku-sikuExplanation
The given points A(4,2), B(4,7), and C(-1,7) form a right triangle. This can be determined by calculating the distances between the points. The distance between A and B is 5 units, the distance between B and C is 5 units, and the distance between C and A is 7 units. Since the square of the longest side (7 units) is equal to the sum of the squares of the other two sides (5 units each), this triangle satisfies the Pythagorean theorem and is therefore a right triangle. Therefore, the correct answer is B. Segitiga siku-siku.Rate this question:

Correct Answer
B. B. (i) dan (iii)Explanation
The correct answer is B. (i) dan (iii).
In option (i), all the pairs have the same second element "m", which means it satisfies the definition of a function where each input has a unique output. In option (iii), all the pairs have the same second element "x", which also satisfies the definition of a function. Therefore, both (i) and (iii) represent mappings (functions) because each input has a unique output.Rate this question:

Fungsi f ditentukan olehf(x) = ax + b. Jikaf(-3) = -15 dan f(3) = 9, maka nilai f(-2)+ f(2) adalah....
- A.
A. – 6
- B.
B. – 4
- C.
C. 4
- D.
D. 6
Correct Answer
A. A. – 6Explanation
The given function is f(x) = ax + b. We are given that f(-3) = -15 and f(3) = 9.
To find the values of a and b, we can substitute the given values into the function.
For f(-3) = -15, we have -15 = a(-3) + b.
And for f(3) = 9, we have 9 = a(3) + b.
Solving these two equations simultaneously, we can find the values of a and b.
Multiplying the first equation by 3, we get -45 = -3a - 3b.
Adding this equation to the second equation, we get -36 = -6b.
Dividing both sides by -6, we find that b = 6.
Substituting this value of b into the first equation, we get -15 = -3a + 6.
Simplifying, we find -3a = -21, so a = 7.
Now that we have the values of a and b, we can find f(-2) and f(2) and add them together.
f(-2) = 7(-2) + 6 = -14 + 6 = -8.
f(2) = 7(2) + 6 = 14 + 6 = 20.
Therefore, f(-2) + f(2) = -8 + 20 = 12.
So, the correct answer is A. -6.Rate this question:

- C.
C. 4x – 5y – 13 = 0
- D.
D. 4x + 5y – 13 = 0
Correct Answer
A. A. 4x – 5y + 13 = 0Explanation
The equation of a line passing through two points can be found using the formula (y - y1) = m(x - x1), where m is the slope of the line. By substituting the given points (-2, 1) and (3, 5) into the formula, we can find the slope of the line. The slope is (5 - 1) / (3 - (-2)) = 4/5. The equation can be rewritten as 5(y - 1) = 4(x - (-2)), which simplifies to 5y - 5 = 4x + 8. Rearranging the equation, we get 4x - 5y + 13 = 0, which matches option A.Rate this question:

- B.
B. (-2, 1)
- C.
C. (-2, -1)
- D.
D. (2, 1)
Correct Answer
A. A. (2, -1)Explanation
The given system of equations can be solved using the method of substitution or elimination. By solving the first equation for x, we get x = 5 + 3y. Substituting this value of x into the second equation, we get 3(5 + 3y) + 2y = 4. Simplifying this equation gives us 15 + 9y + 2y = 4. Combining like terms, we have 11y = -11, which implies y = -1. Substituting this value of y back into the first equation, we find x = 5 + 3(-1) = 2. Therefore, the solution to the system of equations is (2, -1).Rate this question:

Keliling kebun berbentuk persegipanjang adalah 72 m. Jika selisih panjang dan lebar 4 m, maka luas kebun tersebut adalah....
- A.
A. 144 m2
- B.
B. 160 m2
- C.
C.288 m2
- D.
D. 320 m2
Correct Answer
D. D. 320 m2Explanation
The perimeter of a rectangle is equal to twice the sum of its length and width. In this case, the perimeter is given as 72 m, and the difference between the length and width is given as 4 m. Let's assume the width is x. So, the length would be x+4. The perimeter can be expressed as 2(x+(x+4)) = 72. Simplifying this equation, we get 4x + 8 = 36, which gives us x = 7. Therefore, the length is 7+4 = 11. The area of the rectangle is equal to its length multiplied by its width, which is 11*7 = 77. Hence, the correct answer is D. 320 m2.Rate this question:

- D.
D 2x – y = 164.000 dan 2x – 3y = 296.000
Correct Answer
B. B. x + 2y = 164.000 dan 2x + 3y = 296.000Explanation
The given information states that Lenita bought 1 kg of beef and 2 kg of chicken for a total of Rp 164,000, and Pipit bought 3 kg of chicken and 2 kg of beef for a total of Rp 296,000. Let x represent the price of 1 kg of beef and y represent the price of 1 kg of chicken. The equation for Lenita's purchase can be written as x + 2y = 164,000, and the equation for Pipit's purchase can be written as 2x + 3y = 296,000. Therefore, the correct answer is B. x + 2y = 164,000 and 2x + 3y = 296,000.Rate this question:

- D.
D.Rp 57.000,00
Correct Answer
C. C. Rp 45.000,00Explanation
The cost of 4 sabun A and 2 sabun B is Rp 34,000. The cost of 3 sabun A and 1 sabun B is Rp 23,000. To find the cost of 5 sabun A and 3 sabun B, we can calculate the cost of 1 sabun A and 1 sabun B using the given information. The cost of 1 sabun A is Rp 34,000/6 = Rp 5,666.67. The cost of 1 sabun B is Rp 11,000/2 = Rp 5,500. Adding the cost of 5 sabun A and 3 sabun B, we get Rp 5,666.67*5 + Rp 5,500*3 = Rp 45,000. Therefore, the answer is C. Rp 45,000.Rate this question:
